#### Cylinder Basic Scan - Measured Point Method

To generate a cylinder without the use of CAD data:

1. Take three hits on the surface to find the axis vector of the cylinder.

2. Take three additional hits in the hole (or on the stud). PC-DMIS calculates the diameter of the cylinder using all three hits.

You can take additional hits. PC-DMIS uses the data from all of the measured hits.

- The Centroid that appears in the BASICSCAN dialog box (Insert | Scan | Cylinder) is the calculated center of the hole (or stud).

- The CutVec is the cylinder axis.

- The InitVec of the cylinder is calculated based on the first of the last three hits that are used to calculate the diameter of the cylinder.

- The angle is calculated as the angle of the arc from the first hit used to calculate the diameter of the cylinder to the last click.
